Enzyme linked immuno-sorbent assay is a technique used in detection of which of the following diseases?

Acquired immunodeficiency syndrome (AIDS)

The correct answer is Option (1)- Acquired immunodeficiency syndrome (AIDS)

Out of the options you listed, Enzyme-linked immunosorbent assay (ELISA) can be used in detection of:

• Acquired immunodeficiency syndrome (AIDS)

ELISA is a common technique used in diagnosing HIV, the virus that causes AIDS. The enzyme-linked immunosorbent assay (ELISA) is an immunological assay commonly used to measure antibodies, antigens, proteins and glycoproteins in biological samples. Some examples include: diagnosis of HIV infection, pregnancy tests, and measurement of cytokines or soluble receptors in cell supernatant or serum. ELISA assays are generally carried out in 96 well plates, allowing multiple samples to be measured in a single experiment. These plates need to be special absorbant plates (e.g. NUNC Immuno plates) to ensure the antibody or antigen sticks to the surface. Each ELISA measures a specific antigen, and kits for a variety of antigens are widely available.

ELISA is not commonly used for diagnosing kidney cancer, malaria, or rheumatoid arthritis. There might be other tests used for these conditions.
